so the solution will not be contaminated or changed during the reaction
The new substances formed during a chemical reaction are called Products.
The hypothesis is a personal explanation of what youbelieve will happen during an experiment before you proceed in doing that experiment.
like have i al ready done this or like why is this happening and that's when you do an experiment
a variable
The observations and measurements recorded during an experiment are called data. It is important to keep accurate data in order to understand the results of the experiment.

Observation is important in science because it allows for recordings during an experiment. It also is used as support for hypotheses.
becuase because

Clutter leads to accidents, and accidents can ruin the experiment.

The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
